Thanks for sharing that knowledge. Yes, that was just the first "proof-of-concept" code I personally wrote. A /whole/ lotta further development work by many different people, and some changes with Colab itself, have occurred since.

Personally, I never mount Google Drives within Colab Instances, so definitely others (such as yourself) are more knowledgeable about the current state-of-the-art in that space.

Since the poster had asked about mfaktc, not gpuowl, I managed to make that work, but I had a heck of a time getting it to compile. Still, for reference, here is my mfactc wallet:

%cd '/content/drive/My Drive/mfaktc1'
!chmod 755 ../bin/*
!cp ../bin/libcuda* /usr/lib/x86_64-linux-gnu/
!python2 ../bin/mlfloop.py -u staffen -p YeahRight -U staffen -P NoReally -g 600 -e 76 -t 0
!cat worktodo.txt
!../bin/mfaktc.exe

And here is the code I put together (starting from ATH's gpuOwl compile code, and modifying from there) to get the cursed thing to compile for a Tesla V100. Note that I put a copy of the Makefile from the tfaktc folder on my google drive, that had a line for compute_70 in it. 75 did not work, nor do any of the ones that come in it. It uses mlfloop.py to fetch work from gpu72 and upload it to primenet at the begining of the session. I used python2 to run that, because translating it into python3 made my hair turn grey.

I've spent the last few Saturday mornings trying to figure this out (I haven't done much coding since college), and I'm able to get almost everything to work, but I get stuck on the following lines

!cp -r '/content/drive/My Drive/bin/makefile' ./
!make

I get this error:

Reading makefiles...
Reading makefile 'makefile'...
make: *** makefile: Is a directory. Stop.

I'm not sure what exactly is holding things up (I don't know why it thinks makefile is a directory). Or is there an alternative, such as sharing the executable that you were able to create? Thanks!

Try:
Code:
!ls -ld makefile
That should tell you what it really is. If it is a file try posting the contents here (assuming it's not too big).
